Answer:

<h3>               YES</h3>

Step-by-step explanation:

relation is a function if we have y for every x from domain and for one x we have one and only one y

x = 1  --> y = 2

x = 2 --> y = 2

x = -2 --> y = 2

no x-es without y-es

and no two the same x-es with one y

so this relation is a function

Answer:

Nearly [too low]

Step-by-step explanation:

*<em>Twelve</em><em> </em>→ dozen

<em>Twenty-four</em><em> </em>→ 2 dozen

(24)(4) = 96

Add this to 97 to get 193.

196 > 193

This is a little too low. Choose the third option though.

Without sketching the graph solve -6-x&gt;10
kompoz [17]

Answer:

x < -16

Step-by-step explanation:

-6-x>10

adding 6 in both sides:

-6-x+6 > 10+6

-x > 16

If you want to remove the negative sign from x, you'll have to change the inequality sign.

x < - 16

Hope this helps.
